The original Lisp. Invented by John McCarthy et al at MIT in the late 50's. Followed by LISP 1.5.

The second version of Lisp, successor to LISP 1. Developed at MIT in 1959. Followed by LISP 1.75, LISP 1.9, Lisp 2 and many other versions.

BBN LISP (also stylized BBN-Lisp) was a dialect of the Lisp programming language by Bolt, Beranek and Newman Inc. in Cambridge, Massachusetts.

(lisps, lisping, lisped)

<language> LISt Processing language. (Or mythically "Lots of Irritating Superfluous Parentheses"). Artificial Intelligence's mother tongue, a symbolic, functional, recursive language based on the ideas of lambda-calculus, variable-length lists and trees as fundamental data types and the interpretation of code as data and vice-versa. Data objects in Lisp are lists and atoms. Lists may contain lists and atoms. Atoms are either numbers or symbols. Programs in Lisp are themselves lists of symbols which can be treated as data. Most implementations of Lisp allow functions with side-effects but there is a core of Lisp which is purely functional. All Lisp functions and programs are expressions that return values; this, together with the high memory use of Lisp, gave rise to Alan Perlis's famous quip (itself a take on an Oscar Wilde quote) that "Lisp programmers know the value of everything and the cost of nothing". The original version was LISP 1, invented by John McCarthy <jmc@sail.stanford.edu> at MIT in the late 1950s. Lisp is actually older than any other high level language still in use except Fortran. Accordingly, it has undergone considerable change over the years. Modern variants are quite different in detail. The dominant HLL among hackers until the early 1980s, Lisp now shares the throne with C. See languages of choice. One significant application for Lisp has been as a proof by example that most newer languages, such as COBOL and Ada, are full of unnecessary crocks. When the Right Thing has already been done once, there is no justification for bogosity in newer languages.

<language> A dialect of Lisp defined by a consortium of companies brought together in 1981 by the {Defence Advanced Research Projects Agency} (DARPA). Companies included Symbolics, Lisp Machines, Inc., {Digital Equipment Corporation}, Bell Labs., Xerox, Hewlett-Packard, Lawrence Livermore Labs., Carnegie-Mellon University, Stanford University, Yale, MIT and USC Berkeley. Common Lisp is lexically scoped by default but can be dynamically scoped. Common Lisp is a large and complex language, fairly close to a superset of MacLisp. It features lexical binding, data structures using defstruct and setf, closures, multiple values, types using declare and a variety of numerical types. Function calls allow "&optional", keyword and "&rest" arguments. Generic sequence can either be a list or an array. It provides formatted printing using escape characters. Common LISP now includes CLOS, an extended LOOP macro, condition system, pretty printing and logical pathnames. Implementations include AKCL, CCL, CLiCC, CLISP, CLX, CMU Common Lisp, DCL, KCL, MCL and WCL.

A lisp is a speech impairment in which a person misarticulates sibilants (, , , , , , , ). These misarticulations often result in unclear speech.
